Some users are experiencing problems with black / frozen screens; after upgrading to iOS 9.
More specifically, your iPhone ( or iPad) screen may go black when you launch an app. Users stated that this problem occurs when an app is launched the first time. Some users also stated that this black screen problem starts occurring after making a call with Voice Control.
It seems that this is not a random issue. We were able to replicate this bug by doing this:
- Disable Siri (if it is enabled) by going to Settings > General > Siri.
- Lock your iPhone screen by pressing sleep/wake button.
- Press and hold the Home button to activate Voice Control
- Call somebody using Voice Control (you may say ‘call Tom’, for example)
- Talk then end the call.
- Now you will experience this bug. Simply open an app that wasn’t previously opened. Opening any app will result in a complete black screen.
It seems that mostly iPhone 6, iPhone 6 Plus, iPhone 5, iPhone 5s and iPhone 5c users are affected by this issue.
If you are experiencing this display bug, here is how you can troubleshoot:
- We were able to fix this bug by simply enabling Siri. If Siri is disabled, go to Settings > General > Siri and turn Siri on.
- Tap Settings then Display & Brightness then change Display Zoom View from “Standard” to “Zoomed” or “Zoomed” to “Standard”; depending on your original setting.
- If the tips above does not solve this problem, try this: Tap Settings; Display & Brightness then tap Display Zoom View and choose Zoomed and tap “Set”. A message will say “Changing Display Doom will restart iPhone” and tap “Use Zoomed”. After your iPhone restart, now tap Standard > Set and “Use Standard.
- Tap Settings > Display & Brightness then disable “Auto-Brighness”.
- Restart your device by pressing and holding the on/off button.
- Force your device to restart by pressing on/off and home buttons together until you see the Apple logo.
- Remove and reinstall the app that you are having problems with. To do this, tap and hold the app, then tap the (x) sign when it jiggles. Then go to the App Store and re-download the same app.

Thank you, it solved my problem
I have the same issue with my iPhone 6.
I ‘ve tried everything that you describe and none of them are a solution.
They temporary solutions until you use voice commands again.
i have the same issue.
I have experienced the same issue except that it only happens to me after the phone has been left out in the car all day and the phone is hot.
Many thanks!!! The first method solved this annoying issue.
Glad to love iOS 9… now! 🙂
i have a simmilar issue. i”ve tried everything. can”t fix it. everytime when i turn it on the apple logo appears fur less than a second and then dissapear. but i can hear it turning on. i can remote acces the phone via itool but can”t solve the problem. i have an iphone 4s updated to ios 9.0.2 . can i downgrade to 8.4.1 to solve the problem at least?
My Iphone 5 is doing this.
It’s doing it with ALL apps, even the inbuilt ones so deleting and re-installing apps isn’t a solution.
As already said. All the stated solutions only work until using voice command (in the car for me) which is almost EVERY time I’m in the car. This problem is very annoying and needs to be addressed.
Awesome – had this issue for weeks now since updating 5c to IOS9; every time I would open an app the screen would blackout and i’d have to close and reopen. All solved by just switching on Siri!!!
I’ve have searched the web and finally somebody admits that this problem exists! Non of the above works, I have to turn the phone off and on again for certain apps to work. Now I’ll refrain from using the occasional “Call wife” voice command 🙂
What if you have vision issues and require the zoomed feature..
I tried all the above things in my iPhone 5 (iOS 9.0.2). But no use.
After changing the settings, I switched off and then after switching on again, It is black again. Even the Apple logo is not seen while starting the phone. !!
Experienced the problem on a 4S.
I had this issue but it only occurs when I have bluetooth switched on, I have to switch it off when I’m not in the car and the phone is fine. Be nice if Apple could sort this out though!
I am having this issue on my 6S – with a completely black unresponsive screen – with Siri randomly saying he did’ catch that. I did not do any of the steps to recreate the problem. The alarm I set went off and I turned the alarm off. I didn’t do anything else, yet 30 minutes later the phone screen is black.
The steps above are worthless with a black unresponsive screen. I can’t even force a power down.
Same here. How can I take steps to remedy when the screen is totally black?
my iphone 4s is open but the screen is black. i have auto update. can someone help me please 🙁
guys please help me. my iphone 4s auto updated to ios 9.2 and my screen went black. i can hear siri but i can’t do anything because i can’t see anything. help me pleaseeee :((
Power+Home+Volumen Down button option worked for me on iphone 4s with iOS 7.1
Thanks
YOU’RE A LIFESAVER
This junk 6s plus goes black after i slide to unlock and huge app icons appeared and no status bar?? Tried everything so I smashed the new 128 gb!! Problems solved, well wasted money lol
This sucks
I had the same problem and found the solution at last. Nothing listed here fixed the issue but I noticed I had gibberish in the spelling corrector suggestion band right on top of the keyboard when in the SMS screen, so all I did is to go SETTINGS > GENERAL > RESET (the last item at bottom) > “Reset Keyboard Dictionary” and confirm. I’m not sure how the dictionary got corrupted, maybe the kids typed a bunch of characters in there, but it was very very long strings of mixed characters and it looks like it made the iPhone hang on black screens when switching between apps. I didn’t even have to reboot the phone, been using it for an hour in various apps and it’s is back to normal! Hope it helps somebody else 🙂
I have same issue and it make me so annoying and have to swift it off and on again, it’s really border cause i have to search and retrieve all info in my message all the time, when it gone blank inself i can’t carry my work anymore..
I am thinking to reformat my iPhone 6 Plus. My Previous Iphone 4s having same problem and after I reformatted it, it’s ok, anyway I seldom use it the message is still there until today. Thank you
